7c994c366c Process picture aspect ratio changes in H.264.
This fixes playback of such streams with ffplay (but does not affect
current ffmpeg).

5b0fb5244d Store intra4x4_pred_mode per row only.
about 5 cpu cycles slower in the local code but should be overall faster
due to reduced cache use. (my sample though has too few intra4x4 blocks
for this to be meassureable easily either way)

c988f97566 Rearchitecturing the stiched up goose part 1
Run loop filter per row instead of per MB, this also should make it
much easier to switch to per frame filtering and also doing so in a
seperate thread in the future if some volunteer wants to try.
Overall decoding speedup of 1.7% (single thread on pentium dual / cathedral sample)
This change also allows some optimizations to be tried that would not have
been possible before.

e1e949026e Split cavlc out of h264.c.
Seems to speed the code up a little...
The placement of many generic functions between h264.c and h264.h is still open
Currently they are a little randomly placed between them.
